Tire concern
I have a 5th wheel that is 2 years old and has about 6000 miles on the tires. The rear axle tires have dimbles on the sidewall. Is that the beginning of tire failure?
Forum Discussion
Country of origin, tire age or brand name has nothing to do with tire undulations. They are a common byproduct of radial tire construction. Sidewall indentations/undulations are more noticeable in tires with taller sidewalls or operate at higher inflation pressures. Sidewall indentations/undulations are conditions that do not affect the performance of the tires."
